In this book, Ken Camp starts out with a history and overview of telecommunications that puts the reader up to speed very quickly. Next, he engages in a useful discussion of Internet Protocol (IP) networking and the Internet, with a little history and a look at the protocols. A discussion of the transmission of voice in IP packets and telephony protocols gets to the meat of the subject. Then comes a brief look at the practical considerations of using IP telephony: traffic engineering, quality-of-service issues, and gateways between networks. Finally, premise-based telephony and network-based IP telephony services are discussed and evaluated, along with their future. The addition of an acronym and abbreviation list in Appendix A is outstanding.
IP telephony has potential for the future of business, but you'll need to understand the technology and the issues if you want to reap the benefits. Technology will continue to evolve: The key is to take advantage of IP telephony at the right time, and that time is now. This book will pave the way to that level of confidence and put you in the driver's seat! John Vacca
